Summary
The primary hypothesis being tested in this trial is that ischemic stroke patients in posterior circulation at 4.5 - 24 hours post onset of stroke will have improved clinical outcomes when given intravenous tissue plasminogen activator (tPA) compared to standard care.

within 1 hour before or post CT, or the vascular examination indicates that there are
symptomatic stenosis or occlusion of large posterior circulation vessels, or the
perfusion image indicates that there are symptomatic hypoperfusion changes in the
posterior circulation area.
